Dwight Silverman says to look for a new look for the Chron's blogs soon:
We'll be moving the TechBlog, MeMo and Richard Justice's blog to new software designed specifically for blogging. It will allow readers to post comments, and will include trackback, so you can can see what other sites are saying about individual postings.
Any new blogs we create -- and we're adding quite a few in the coming months -- will use this software.
When this happens, the Web address for the blogs' home pages will change, as will the RSS feed URLs. We'll post notices in each of the old blog locations letting you know where the new ones can be found.
